Any Drink Called For Effect:
You display a beautiful tea kettle and empty glasses hanging on a beautiful display stand. You ask a random audience member to name any drink. You pick up and empty the glass and pour said drink from the kettle! Next, you ask another person to name another drink, you pick up another empty glass and pour their drink from the same kettle! You can repeat this over and over again, and each time the illusion becomes more baffling!
